Vl'hile I have shown in the drawingaa friction-clutch C wherein the-inner member is .pinned to ,shaft D within .the hollow flywheel member 1Q, which in turn is pinned to shaft B and having Inclinedsurfacea against which the seguental cone surfaces of the in- 'ner nzernher l0 normally engageby reason of the tension exerted hyspring 13,surround ing the'cxid of shaft B and hearing against and the axle of i '1S maybeit will readily belet-.en that my device may be adapted to other elnlches, and the nfxodiliea-` tions necessary fousuch adaptation ivill readily Suggest theniseli'es .to persons skilled in them-t. i

The shaft D or the removable portion thereof is provided witl'a spiral or vworm 14,

having on the right-hand spiral as shown in Fig. 1, a pivoted tongue or gute adapted to 'lar. r ber is sufficient to advance shaft 'D far t enough to free the inner clutch member 11 o which forms a collaHsurtac-e, is determined bj' the position of the collar 47. hereinafter i turned upward to enter the spirals of worm 14,

described. The relative position of these i partsy is such that when the roller r is turning on the collar tand the last .spiral of worin 14 closelyn einst the colhir47.

On roc i shaft 36, held in suitable bearings against ongitudinal movement therein, x isA mounted a tilting and slidable member M, i

isrollerr, adapted when member Mis tilted or draw lever 18 by means of link 43 forward on its fulcrum 40 against collar 47, (on the surpoint bearing,) retract spring 13, and disenold the members in this unlocked position' b means of the collar formed on vi'orin 14 iby worm and collar 14. A pin 4l on rock-shaft 36 and a slot 42 in member M allows the latter longitudinal movement independent of ited up-anddown tilting movement suiiicient to allow roller r alternately to clear and engage the spirals of worm 14.

vl'ivoted at one dnd at the point 40 to a which inem er M is connected by link 43,V loosely pinned to lever 1851. 44 and to M at 45, no as to permit rre'mber M a lilited tilt ing play sufficient to allow roller rto be spirals of worm 14. When lever 18 is nroved on the point 40 as a fulcrum, it will force member M to slide upon rock-shaft 36. A loop 46, 2, in lever 18 embraces shaftD,

surface 47. I prefer to rovide the surface of loop 46 adjaceritto col ar 47 with a curved pointed bearing, as shown in Fig. l. To the end 48 of lever 18 'is pivoted piston `491 in,A

the lef/der lili is to elastifcally cushion or e resist action o ,s 13 as theyiilutcmhgntembers are interlockeiillimg` The clutch C may be o rated bv foot-leoot-lever E, adapted to turn freely on shaft 19 as s fulcruin, is connected to rock-shaft 17, which it throws pr rocks by means of a'link 50, Fig. 7, and an arm 51, 'votllly connected at 52 and 53.

17 is suitably supported substanrnent with the rear or leftfhand tisllg;7 at right angles to shaft D and adjacent to lever 18. 0n rock-shaft 17 at a point beyond the fulcruni 4U of lever 18 is an arm 23, adapted to thrust lever 18 against collar 47 and unlock the clutch.

Hand-lever F, operstinr shaft 19 to rock f arm 12, and thus shift the gear connections or rod I-l, comprises a hand-grasp 30, handgrasp spring e, rod 31, catch d, springs s',

and ratchet e for locking the gcar-shifting mechanism in the desired position. In order to tie the gear-shiftirig mechanism to the clutch mechanism so that the fomier cannot be opi-rated without unlocking the clutch C,

, l provide a rod, rock-arm and link connections between lever F and rock-shaft 36 comprising rock member 26 on lever F, secured to link 27 at 32, which, in turn, is pivoted to one end of rod 25 at 33, at the other end of which is pivoted at 34 'one end of .a rockarm 35, rigidly secured to shaft 36.A Rod 25 inc vextend across the machine in any convenient manner, though to obtain a compact construction I prefer to make shaft 19 hollow and curr)v rod 25 through it to arm 35, as shown in the drawings.

The operation of my device is as follows: When it is desired to release the clutch without changing gears, the foot of the operator is placed upon the pedal-lever E, causing the lever to turn upon shaft 19 as a fulrum,

thereb3r rocking rock-shaft 17 and causing arm 23 to contact with lever 18 and force the l lever 18 against collar 47, moving the shaft D forward and disengaging member l1 from the {by-wheel member l0. In this,y position the piston 49 in dash-pot G is drawn out to the forward end thereof. The clutch may be thusheld unlocked until the foot of the operator is removed from the pedal E. It

is sufficient will be understood that there play1 in the pivots and ins 44 and 45 to per mit member M in the a ove-described o tion to pass over the spirals without engaging the worm. When the foot is removed from the pedal of lever E, the tension oT spring 13 within the clutch 'C forces the inner member 11 to interlock with the member 10. The tension of this spring, however, is opposed and iieldingljv resisted by the compressed air in dash-pot G, which supports lever 18 in this withdrawing movement, and through collar 47 causes the action of the springv 13 to' be elastically ci'hioned, thus insuring gradual locking clutch members without shock or strain. sbiiizpg the gem by means of the hand-le-4 ver. which o rates the rod H, the clutch is automatica unlocked. This operation is accomplished through the link, rod, and rock-arm connections 23, 25, and 35, which rock the shaft 36 and lift roller r into engage- Spiral, l irorm V14. This worm being constan y l f rbtgi'ting causes the spiral to engage the roller 13:

peraf4 of the two 'ver 18 and the collar end of the worm 14 l decreased, according as the angle between to automobiles solely, as many changes in ,means of the connection 43," the lever lfi -themselves to those skilled in the art, but

-ed to unlock said clutch, means for opcrat- 1' and move the same, drawing .with it, by

which thenbears against the collar 47 an thruststhe shaft D forward to iuilook the clutch members. As'soon'astlie last or right-hand spiral, vas shown in, Fig. 1, is reached bv the roller r it passes on the outoted tongue t, which forms a collar. In this position the clutch is held unlocked, the Ie maintaining the shaft D in this position. It will be noted that bv pivoting lever 1S at the end 40 and providing-a point-bearing onl loop 46 that the relative distance between point 40 and roller r maj,y be increased and 18 and 43 is increased or decreased. To lock the clutch after the parts Vhave assumed this position, it is merely necessaryY to drop or tilt the member M to releaseroller 'r from the collar oxuworm 14. This is done by rocking the shaft 36 in the opposite direction by means of lever F, connectingrod- 25, arm '35, and link 23.
